I'd do a flood test first: fill it up and let it sit for a week or so to see if it's leaking to begin with.
If it leaks, then you'll have to see where:
if it's leaking where the cracked silicone is, then you'll need to reseal; if the cracked silicone is between the panes of the glass, then you'll have to break down the panes and basically make a new tank out of the panes from the tank.
New silicone doesn't adhere well to old silicone, so a tedious scraping will need to be done.
